DEEE0010312
Cooperative Agreement
Overview
Grant Description
The proposed project will develop a solar calciner receiver system for the production of lime, cement, calcined clay, and activated limestone.
Preliminary technoeconomic analysis has identified a pathway to a levelized cost of heat, LCOH = 0.02 $/KWHTH at internal calcination temperatures of 950°C, which is high enough to serve all the aforementioned product markets.
The three-year project includes lab-scale testing, multi-phase reactor modeling for design and scale-up, and on-sun testing for calcination to 400 KWTH.

Funding Goals
FOR NEXT-GENERATION CSP PLANTS, SETO HAS SET A TARGET TO LOWER THE COST OF ELECTRICITY FROM BASELOAD PLANTS, WITH GREATER THAN 12 HOURS OF STORAGE, TO $0.05/KWH BY 2030. THIS REPRESENTS, APPROXIMATELY, A 50% REDUCTION OF EXISTING COSTS. ALTHOUGH THIS TARGET IS AGGRESSIVE, THERE ARE MULTIPLE PATHWAYS TO ACHIEVE IT. ALL PATHWAYS REQUIRE SIGNIFICANT IMPROVEMENTS ACROSS SETO’S RESEARCH AREAS, BUT GREATER PROGRESS IN ONE AREA CAN ALLOW FOR MORE MODERATE CHANGE IN OTHERS. THESE INTERDEPENDENCIES AND TRADE-OFFS AMONG COST- AND PERFORMANCE-IMPROVEMENT FACTORS CREATE MANY OPPORTUNITIES FOR TECHNOLOGY DEVELOPMENT. FIGURE 3, BELOW, DESCRIBES ONE POTENTIAL PATHWAY TO $0.05/KWH BY 2030.
